(H) Between Apirl and May, the increase in the number of vistors was at a much slower pace than in the previous three mounths.

Answer 1

A. In the last /past 应用现在完成时：have been off..
B.was 改成has been
C. rocketing 改成 increasing，
我认为数字是增加（increase）不是上升（rocket），这个不确定
D.surging by 500% （百分数前应加by 或者to ，说明上涨了或上涨到）
E.rose 改成 has （had) risen
F.rose 改成 have risen
G.shaper 改成 sharp （“明显”的意思）
H. than后加 that in the previous three mounths
I.were 改成have been being（表示情况一直是这样的）
原因 for most of the year应用现在完成时吧，并且现在情况仍这样发展，就用现在完成进行时

我不是高手，但想帮忙，希望能为你提供些帮助
